handle references for PHPCR ODM documents

[takeit]

Doing:

$this->addReference('test', $document);

throws an exception:

[Symfony\Component\Debug\Exception\UndefinedMethodException]
  Attempted to call an undefined method named "getDocumentIdentifier" of class "Doctrine\ODM\PHPCR\UnitOfWork".

when using references with PHPCR ODM documents.

The PHPCR ODM UnitOfWork class doesn't have the method getDocumentIdentifier. There is getDocumentId instead. MongoDB ODM seems to use getDocumentIdentifier method in its UnitOfWork class but not in PHPCR.

Please, let me know if its enough.

@takeit Is this the only thing that prevent you to use the data-fixture with the ODM ?

[takeit]

@mikeSimonson I use it with PHPCR ODM in project I work on anyway. Even without the references that't not a blocker for me atm and it doesn't prevent me to use it.

@takeit Can you add a test for it ?

@mikeSimonson This PR seems obsolete: https://github.com/doctrine/data-fixtures/blob/3a1e2c3c600e615a2dffe56d4ca0875cc5233e0a/lib/Doctrine/Common/DataFixtures/ReferenceRepository.php#L68

Thanks @kojiDev! This was indeed fixed in #255. Closing here.
